Got basic VPN background? Yes? This is your book

Ideally, you should understand basic crypto and have played around with VPNs before reading this book. Have you configured local, gateway, and Road Warrior VPNs before? If so, this book is ideally suited for review and for filling in any gaps in your knowledge. There are some grammatical errors, but nothing serious. Some illustrations, particularly those in the Deployment Scenarios section, don't mesh with the text and require correction to make sense. There is enough information in the text to resolve these errors and pencil in corrections, but isn't this supposed to be a second edition? Speaking of mesh, I was surprised to see no mention of the highly useful mesh equation n(n-1)/2 anywhere. Instead, a more junior-level illustration is used. A combination of both would have been more appropriate for this book. Overall, this is a useful book that will take your basic knowledge of IPSEC to the next level.
4 stars, as the book nevertheless is a productive discussion with two knowledgeable practitioners of IPSEC.
